tinydate.js[v0.3] 新增了字符串格式化为日期对象的函数

更新说明

1. 加入了String类型的扩展成员 convertToDate() 可以直接将 字符串格式的日期转换为Date对象。
2. 加入了String类型的扩展成员 convertToTimeSpan() 可以将 字符串格式的日期转换为TimeSpan对象。
3. 修复了日期格式化为字符串的format函数中的bug。

tinydate.js v0.3

Date.prototype.format = function (fmt) {var o = {"M+": this.getMonth() + 1,                 //月份 "d+": this.getDate(),                    //日 "H+": this.getHours(),                   //小时 "m+": this.getMinutes(),                 //分 "s+": this.getSeconds(),                 //秒 "q+": Math.floor((this.getMonth() + 3) / 3), //季度 "f+": this.getMilliseconds()             //毫秒 };if (/(y+)/.test(fmt)) {fmt = fmt.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));}for (var k in o) {if (new RegExp("(" + k + ")").test(fmt)) {fmt = fmt.replace(RegExp.$1, (RegExp.$1.length == 1) ?
